Roughly
chop all ingredients in a food processor fitted with a metal blade, or
mix in a large bowl, mashing the beans as you go. Form into small
patties (this will be messy, as the mixture can be quite loose) and
dust with flour. Film a large frying pan with peanut oil, and sauté the
black bean cakes until nicely browned on each side. Serve with
guacamole.
